The pen can function at the default calibration or at a calibration set by you or by another user. It is recommended that you use the pen only while it is calibrated to your personal calibration settings. Calibration optimizes pen performance for each user.

To calibrate the pen:

Open Control Panel

Double click Tablet PC Settings

On the Tablet PC Settings window, click Calibrate

On the Calibrate pen or touch input screens, select Pen input

Follow the instructions on the screen. The calibration markers are displayed on the screen as big plus sign (+). Tap the pen in the exact centre of each of the calibration markers.

The pen should be the first component to be investigated in the event of a suspected problem with the digitizer. Verify the tip is in good shape (free of chips, excessive wear, etc.) by closely examining it. If there is any doubt, you should change out the tip with a new one or one that is known to be in good condition.

You should also verify that the touch capabilities are not affected. Switch to touch mode and see if the problem still exists. If there are no symptoms present while in touch mode, the pen tip is the most likely suspect. If the problem does persist in touch mode you should run diagnostics and take the necessary steps depending on the results.
